With this commit the compiler will "lower" expressions into exported
variables for values the compiler does not need to know statically
in order to be able to generate a factory. For example:
```
providers: [{provider: 'token', useValue: calculated()}]
```
produced an error as the expression `calculated()` is not supported
by the compiler because `calculated` is not a
[known function](https://angular.io/guide/metadata#annotationsdecorators)
With this commit this is rewritten, during emit of the .js file, into
something like:
```
export var ɵ0 = calculated();
...
provdiers: [{provider: 'token', useValue: ɵ0}]
```
The compiler then will now generate a reference to the exported `ɵ0`
instead of failing to evaluate `calculated()`.

This is needed as the typescript no longer elides type reexports
in the generated code when using transformers.
A nice side effect is that this make summaries shorter and produces
less reexports as we rollup reexports.

Previously, we only did this when setting the `generateCodeForLibraries: false`.
This is needed so that libraries compiled with `generateCodeForLibraries: true` can be used as dependencies of other compilation units.

After this, neither @angular/compiler nor @angular/comnpiler-cli depend
on @angular/core.
This add a duplication of some interfaces and enums which is stored
in @angular/compiler/src/core.ts
BREAKING CHANGE:
- `@angular/platform-server` now additionally depends on
`@angular/platform-browser-dynamic` as a peer dependency.

This change allows users to specify multiple exportAs names for a
directive by giving a comma-delimited list inside the string.
The primary motivation for this change is to allow these names to be
changed in a backwards compatible way.
This also allows to customize the filePaths in `.ngsummary.json` file
via the new methods `toSummaryFileName` and `fromSummaryFileName`
on the `CompilerHost`.
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

The static reflectory check for macro function recursion was too
agressive and disallowed calling a function with argument that also
calls the same function. For example, it disallowed nested animation
groups.

In previous version of tsickle abstract class methods were materialized.
The change resulted in 6Kb savings in angular.io bundle.
This change also required the removal of `@private` and `@return` type
annotation as it is explicitly dissalowed by tsickle.
NOTE: removed casts in front of `makeDecorator` due to:

Refactoring the compiler to use transformers moves the code generation
after type-checking which suppresses the errors TypeScript would
generate in the user code.
`TypeChecker` currently produces the same factory code that was
generated prior the switch to transfomers, getting back the same
diagnostics as before. The refactoring will allow the code to
diverge from the factory code and allow better diagnostic error
messages than was previously possible by type-checking the factories.
These files are needed so that:
- user code can compile even without real codegen
- as tsc transformers cannot create but only change existing files
in the transformation pipeline.
This is required as e.g. `token` from `@Inject` is
accessed in string form via makeParamDecorator
but as a property in the `ReflectiveInjector`.
Closes#16889 as this is a more general fix.
Add source location as a note tag as `<note category="location">path/to/file.ts:start_line[,end_line]</note>`.
`[,end_line]` part is optional and specified only if the end line is different from the start line.

* refactor(core): provide error message in stack for reflective DI
Fixes#16355
* fix(compiler): make AOT work with `noUnusedParameters`
Fixes#15532
* refactor: use view engine also for `NgModuleFactory`s
This is a prerequisite for being able to mock providers
in AOTed code later on.
Template expressions can now use a post-fix `!` operator
that asserts the target of the operator is not null. This is
similar to the TypeScript non-null assert operator. Expressions
generated in factories will be generated with the non-null assert
operator.
Closes: #10855
This code only runs in ES5 mode in the test suite, so this is difficult to test.
However `updateFromTemplate` is being called with a spread operator, as
`...updateFromTemplate(...)`. The spread operator should fail on `null` values.
This change avoids the problem by always returning a (possibly empty) array.

Allows to inherit ctor args, lifecycle hooks and statics from a class
in another compilation unit.
Will error if trying to inherit from a class in another compilation unit
that has an `@Component` / `@Directive` / `@Pipe` / `@NgModule`.
This has the side effect of allowing `@Input` and `@ContentChild`
on the same property if the query is static (see the bug description
for details).
